Wanna-B-Spec Yaris

[deng]

Davis (Dabuu) here with a new username because I wasn't feeling the old one anymore.

I like the idea of building my Yaris to B-spec rules, even if it doesn't show up as an eligible MY in SCCA's GCR. Since I'm not planning to compete, some of my mods will not be legal, hence the wannabe.

I figure this will be a good way to compare my times with legit B-spec-ers.


Cusco Street Zero w/ Center Lock Pillowball Mounts.



F: 7kg/mm / 392lb/in
R: 5kg/mm / 280lb/in

Front dampners are not adjustable, but the rears are 14 way adjustable, already not legal for the class haha. I also like that Cusco supplies a linear spring for the rear.





The rear has been adjusted to max low since I took this picture.

The center lock idea is pretty cool by getting rid of all the rubber bushings up front, but the aluminum teeth for the spanner wrench to lock onto are so weak that the edges start snapping off when torquing down to 80nM. Should've been made out of steel in my opinion.



Previously, I had Konig Dial-Ins in 15x7 +35. They were nice and light, but subjectively they looked okay, and I didn't like cleaning all 12 spokes. So I got rid of half the spokes:



Kosei K1's 15x7 +30 in Miata Spec, ~13.5lbs a wheel. They are hubcentric to the Yaris, easy to clean, and they clear the SE's larger front brake calipers. My rule of thumb is, if the wheels clear a Miata w/ Sport Brakes, they'll clear SE brakes lol.

The wheels are wrapped in 205/50R15 Dunlop Direzza Star Spec ZII. The rears do rub, so I will need to roll them in the future.

I still have a lot of stuff to do before I get back on track, but I'm aiming for TRD Cup @ Streets of Willow on August 19th.
